I'm just finishing lamba x2
The problem is when I connect the lsu 4.2. Just about 30 second after heating, the temperature notification on tunner studio is sensor overheat.
I attached log below. Please help me
Attached the is latest file
Did you change settings to LSU4.2? By default WBO is configured for LSU4.9.
Also you have too low "Ipump actual" compared to "Ipump target". Please check LSU_Ip circuit: U12B, values of R12, R42, R45, R18, R21.

Ah. I also think like you. I've checked for all wire for make sure wiring is correct ( Before I have wrong wiring ) . So I think the U9 (GS8832) is dead, trying replacing U9 but the error still there. The R41 is 6K8 0.1% ( missing in order from LCSC ) I replace it with 6.8K 1% , but still error :D . After that, I just only solder R24 and try testing with LSU 4.9 sensor and the problem fixed

Can someone please help with the current firmware (rusEFI master.2024.04.18.f407-discovery.1378508940) and these wideband controllers. Originally on older firmware and using TS to update the controllers they would work, but randomly go into a error (blue led started flashing), Updating the ECU to 2024.04.18 and then updating the wideband controllers from TS, the wideband does not go into a error now, but there is no reading in TS or on my dash. I get very random readings on the TS where the outline (last position) needle jumps around but the display never moves from displaying zero.

Just adding that the AEM canbus Wideband is working perfectly on the same settings.
